COCONUT, a novel fast-converging MHD model for solar corona simulations: II. Assessing the impact of the input magnetic map on space-weather forecasting at minimum of activity
Barbara Perri, Blazej Kuzma, Michaela Brchnelova +5
This paper is dedicated to the new implicit unstructured coronal code COCONUT, which aims at providing fast and accurate inputs for space weather forecast as an alternative to empi…
COCONUT, a novel fast-converging MHD model for solar corona simulations: I. Benchmarking and optimization of polytropic solutions
Barbara Perri, Peter Leitner, Michaela Brchnelova +5
We present a novel global 3-D coronal MHD model called COCONUT, polytropic in its first stage and based on a time-implicit backward Euler scheme. Our model boosts run-time performa…
Kink instability of triangular jets in the solar atmosphere
T. V. Zaqarashvili, S. Lomineishvili, P. Leitner +3
It is known that hydrodynamic triangular jets are unstable to antisymmetric kink perturbations. The inclusion of magnetic field may lead to the stabilisation of the jets. Jets and…
Structure of the solar photosphere studied from the radiation hydrodynamics code ANTARES
P. Leitner, B. Lemmerer, A. Hanslmeier +4
The ANTARES radiation hydrodynamics code is capable of simulating the solar granulation in detail unequaled by direct observation. We introduce a state-of-the-art numerical tool to…
